CHARLES \V. ZIEGLER, OF SCRANTON, PENNSYLVANIA.

COAL-SEPARATOR.

SPECIFICATION forming part of Letters Patent No. 570,781, dated November 3, 1896.

I Application filed October 7, 1895. Serial No. 564,956. (No model.)

To all whom it may concern.-

Be it known that 1, CHARLES W. ZIEGLER, of Scranton, in the county of Lackawanna and State of Pennsylvania, have invented certain new and useful Improvements in Coal-Sepa rators and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to an improvement in coal-separators, and particularly to the inventions described in patents numbered 27 7,530, 291,123, and 380,156, granted to me May 15, 1883, January l, 1884, and March 27, 1888, respectively, for improvements in machines for separating slate and other like impurities from broken coal; and it consists in the construction of the parts and their relative arrangement and combination with each other in completed machines, as will be hereinafter described, and pointed out in the claims.

In the accompanying drawings, Figure l is a side view. Fi 2 is a top view. Fig. 3 is a central longitudinal section. Fig. 4 is a perspective of the chute and separatingtroughs. Fig. 5 is a perspective view of the adjusting-frame. Figs. 6, 7, and 8 are detail views of the perforated plates and supports. Figs. 9, 10, and 11 are transverse sections on lines 9 9, 1O 10, and 11 11, respectively, of Fig. 3. Fig. 12 is a bottom view of the inclined chutes, and Fig. 13 is a view of the adj ustingbrackets.

The numeral 1 represents the supportingframe of the actuating parts of the machine.

2, 3, and at are stationary cylinders set in the frames 5 and 6. A series of perforated plates are secured in the frames and are provided for the purpose of forming frictionalandnon-frictional surfaces. The upper ends of the plates 7 rest upon surfaces 9, which enable the perforations to become filled with dust, and so present a non-frictional surface, thereby enabling the coal and slate to attain an increased speed down the same until they come in contact with the open perforations on the lower ends of the plates 7 and 8, through which the dust will drop, the coal and slatecontinuing with increased speed until encountering the cylinders 3 and 4, when the coal, which naturally has a greater speed than the slate, owing to its shape, will jump over the openings 3 and 4 between the said cylinders and the adjustable slides 10 and 11, while the slate and other impurities will fall through said openings into the chute 12. After leaving said openings 3 and 4: the coarser slate is very thoroughly separated from the coal, and the liner slate which has escaped the same is likely to pass through the opening 13 and thence down the inclined chute 13 into the trough 14, while the coarser coal will drop through the slightly-larger opening 15 into the chute 15 and thence into the trough l6. Openings 17 and 18 are made still larger, and the coal passing through them is fed into the chutes 17 and 18', and by them conducted into the troughs 19 and 20, respectively. The slate falling through the openings 3 and 4' will run into the central trough 21. The slides are adjustable relative to the said openings, with the exception of the lower one, and are secured to a sliding frame 22, which is fastened to the rock-shaft 23, journaled in the bearings 24:, which are secured to the frames 5 and 6 and are operated by means of the lever 26 and the connecting-rod 25 with the lever 26, pivoted to one side of the frame and to the slide, the opposite side of the same being connected with the shaft 23 by means of the rod 27.

28 represents brackets holding the surfaces 8 and 9 in, position on the frame.

The plates 8 are vertically adjustable to any suitable pitch by means of the brackets 28 and the adjusting-nuts 29 and 30, secured to the cross-bar 31.

It will be observed that the hopper or chute into which the slate and other impurities drop has its outlet upon the same level or incline with the coal, where heretofore the same has had its outlet on the sides of the separator, which is impracticable when a number of separators are so constructed as to set beside each other.
